Available in PDF, EPUB and Kindle. Book excerpt: Low-temperature cracking occurs on some asphalt pavements even though the high-performance grade (PG) binders are applied in asphalt mixtures. It is neither realistic nor economic to solve the problems related to low-temperature cracking on asphalt pavements by purely using high PG binders. Other factors need to be investigated so that this type of distress can be further restrained. This study focuses on investigating the effect of fine aggregates on the low-temperature cracking on asphalt pavements. Low-temperature cracking was monitored and recorded on asphalt pavements in a cold, northeast area of China. Cores were drilled on the spots where low-temperature cracking occurred, and the aggregate gradations of the drilled cores were analyzed in the laboratory. An index called the Fine Aggregate Content Deviation Index (FACDI) was defined as the difference between the actual fine aggregate content and the lower limit of fine aggregate content in the designed aggregate gradation. A positive relation was observed between the FACDI and the cracking index of asphalt pavements. It was demonstrated that the fine aggregate content was another important factor that influences low-temperature cracking of asphalt pavement. The increase of fine aggregate content was found to jeopardize the resistance of asphalt mixture on low-temperature cracking. Based on FACDI, fine aggregate's contents in asphalt mixtures of asphalt layers can be recommended to ensure an asphalt pavement with good low-temperature performance.

Book Synopsis Designing Fine Aggregate Mixtures to Evaluate Fatigue Crack Growth in Asphalt Mixtures by : Anoosha Izadi
Download or read book Designing Fine Aggregate Mixtures to Evaluate Fatigue Crack Growth in Asphalt Mixtures written by Anoosha Izadi and published by . This book was released on 2011 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue cracking is a significant form of pavement distress in flexible pavements. The properties of the sand-asphalt mortars or fine aggregate matrix (FAM) can be used to characterize the evolution of fatigue crack growth and self-healing in asphalt mixtures. This study compares the internal microstructure of the mortar within a full asphalt mixture to the internal microstructure of the FAM specimen. This study also conducts a limited evaluation of the influence of mixture properties and methods of compaction on the engineering properties of the FAM specimens. The results from this study, although limited in number, indicate that in most cases the SGC compacted FAM specimen had a microstructure that most closely resembled the microstructure of the mortar within a full asphalt mixture. Another finding from this study was that, at a given level of damage, the healing characteristic of the three different types of FAM mixes was not significantly different. This indicates that the healing rate is mostly dictated by the type of binder and not significantly influenced by the gradation or binder content, as long as the volumetric distribution of the mastic was the same. In other words, the inherent healing characteristics of the asphalt binder plays a more significant role relative to other properties (e.g. volumetrics) in the overall fatigue cracking resistance of the asphalt mixture.

This book was released on 2012 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies show that the microstructure of the fine aggregate matrix has a significant influence on the mechanical properties and evolution of damage in an asphalt mixture. However, very little work has been done to quantitatively characterize the microstructure of the asphalt binder within the fine aggregate matrix of asphalt mixtures. The first objective of this study was to quantitatively characterize the three dimensional microstructure of the asphalt binder within the fine aggregate matrix (FAM) of an asphalt mixture and compare the influence of binder content, coarse aggregate gradation, and fine aggregate gradation on this microstructure. Studies indicate that gradation of the fine aggregate has the most influence of the degree of anisotropy whereas gradation of the coarse aggregate has the most influence on the direction anisotropy of the asphalt mastic within the fine aggregate matrix. Addition of asphalt binder or adjustments to the fine aggregate gradation also resulted in a more uniform distribution of the asphalt mastic within the fine aggregate matrix. The second objective of this study was to compare the internal microstructure of the mortar within a full-scale asphalt mixture to the internal microstructure of the FAM specimen and also conduct a limited evaluation of the influence of mixture properties and methods of compaction on the engineering properties of the FAM specimens. Fatigue cracking is a significant form of pavement distress in flexible pavements. The properties of the sand-asphalt mortars or FAM can be used to characterize the evolution of fatigue crack growth and self-healing in full-scale asphalt mixtures. The results from this study, although limited in number, indicate that in most cases the SGC (Superpave Gyratory Compactor) compacted FAM specimen had a microstructure that most closely resembled the microstructure of the mortar within a full-scale asphalt mixture. Another finding from this study was that, at a given level of damage, the healing characteristic of the three different types of FAM mixes evaluated was not significantly different. This indicates that the healing rate is mostly dictated by the type of binder and not significantly influenced by the gradation or binder content, as long as the volumetric distribution of the mastic was the same.

Book Synopsis Investigation of Low Temperature Thermal Cracking in Hot Mix Asphalt by : Timothy Aschenbrener
Download or read book Investigation of Low Temperature Thermal Cracking in Hot Mix Asphalt written by Timothy Aschenbrener and published by . This book was released on 1995 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was performed to determine the influence of material properties on the thermal cracking performance of hot mix asphalt (HMA), and to determine the ability to predict thermal cracking from pavements of known field performance. The testing device used to measure the HMA properties was the thermal-stress, restrained-specimen test (TSRST), and the device used to measure the binder properties was the bending beam rheometer (BBR). The laboratory study was conducted to determine the variability of test results as an influence of 1) asphalt cement stiffness, 2) asphalt cement quantity, 3) mixes with various aggregate qualities, 4) aging, and 5) the presence of hydrated lime. The influence of the asphalt cement stiffness was the single largest factor that controlled the test results.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the thermal stress restrained specimen test (TSRST), which was selected to evaluate the low-temperature cracking resistance of asphalt concrete mixtures. The TSRST system includes a load frame, step-motor-driven load ram, data acquisition hardware and software, temperature controller, and specimen alignment stand. An experiment design that considered a range of mixture and test condition variables was developed to evaluate the suitability of TSRST for characterizing low-temperature cracking resistance of asphalt concrete mixtures. Four asphalts and two aggregates were selected for the experiment. The mixture variables included asphalt type, aggregate type, and air voids content; the test condition variables included specimen size, stress relaxation, aging, and cooling rate.
